Climb into a roller coaster and remain seated for an exhilarating exploration of the science and psychology behind America's adrenaline rush. Every year, roller coasters evolve. Some get bigger, faster, longer and more terrifying, hurtling riders upside-down, backwards and down steep descents - sometimes at speeds nearing 80 miles per hour. Momentum, friction, gravity, energy, acceleration, and centripetal force are simply the physical laws behind some of our favorite frightmakers.
